Troubleshooting SymptomsPossible CausesRemedyCoolant leakage • From the bleed hole of the water pump Visually check • Check leaks after about ten-minute warming up.
Removal Removal of the thermostat would have an adverse effect, causing a lowering of cooling efficiency. Do not remove the thermostat, even if the engine tends to overheat.
Inspection 1. Ignition "OFF" 2. Disconnect ambient temperature sensor. 3. Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing of the ambient temperature. 1. Sensor Ground2.
Inspection 1. Ignition "OFF" 2. Disconnect the connector of temperature control actuator. 3. Verify that the temperature control actuator operates to the hot position when connecting 12V to the terminal 3 and grounding terminal 7. Verify that the temperature control actuator operates to the cool position when connecting in the rev
